/* Brand 2.0 blog article.
   brand.css already carries the editorial vocabulary the customer stories use:
   .splash, .hero-grid, .kicker, .dek, .attrib, .statstrip, .story-body, .lede,
   .turn, .pullquote, .final, .faq, .related, .close. A blog post needs four
   things those pages never needed: in-article headings, inline source links,
   lists, and a takeaways block. Those are the only rules here.

   Scoped to this stylesheet rather than added to brand.css so a blog change
   cannot touch the 25 pages that load brand.css. Loaded after brand.css. */
